Examples of this species were captured by Mr. Smith in Mexico during the months of 
February, March, and April, 1888. In the males the whitish lines are very indistinct, 
the primaries being also considerably narrower than those of the females. Walker's 
type of B. semialba is now in the Oxford Museum.
